TECHNICAL FIELD [0001] The present invention relates to a mat type cosmetic composition,

As a lip cosmetic product, a mat type formulation has the advantage of natural color development without light, but it has a limitation in expressing a clear and bright color, and has a disadvantage that the lip is easily dried due to the mat formulation. In recent years, in Korea, lip products having a high coloring power, a moisturizing effect, and a unique feeling of appearance are favored, and it is difficult to produce a clear color, and the position of dry mat type lip cosmetics is getting narrower. Therefore, development of a lip composition that provides a moisturizing feeling while maintaining a mat type formulation is required, and various studies are being conducted based on the demand of such a market.

In order to overcome the problems of the prior art, the present inventors have developed a mat type liquid lip containing silicone elastomer and silicone oil as an oil phase and an absorbent powder and a polyol as a water phase.

The present invention provides a mat type lip cosmetic composition having excellent moisture retention.
